PRODUCTION Of HE McKEESPORT GAS POOL. 
By 


J, French Robinson 


introduction, 


For many years Pennsylvania has been a large producer of natural 
gas. Allegheny County has produced considerable gas but not until 
djugust, 1919, did the McKeesport Gas Pool come into very great promi- 
nence, The McKcesport Gas Pool is located in Allegheny County near 
the city of Uae csoart. 15 miles southeast of Pittsburgh at the 
junction of the Youghiosheny River with the Mononsahela, 

The Bureau of Topographic and Geological Survey is receiving 
many inquiries relative to the production of this pool and therefore 
it has been deemed advisable to issue a bulletin giving the productior 
to date, A detailed study of the field has been made, and a histori- 


cal report will be published later,

STRUCTURAL LOCATION 


The term "McKeesport Gas Pool" is very vague, but in. 
this reyvort it is considered to include all the territory on 
both flanks and top of the southwestern extension of the Murrys- 

? 


ville anticline in Versailles township, enc portions of Portyue , 
Lineoln and Elizabeth townships, The intense crilling, however, 
has not spread over 500 eeres and has been in the neighborhood 
of Vorsailles, Snake Hollow, and Five Ficlés. Development has 


¢ 


now extended in all directions, towards the Bellevernon anti- 
cline on the sovtheast, the Pin Hook snticline on the northwest, 
and for many miles in cither direction along the Murrysville 


anticline. 
DEVELOPMENT 


The Mexcesport Gas Pool became a commercial pool on 


? 


August 29, 1919" when the "big gusher", (the Foster and Brendlce~ 


5 NE 


fouls 


Hamilton #3 woLl , was turned into the Peoples Natural Gas 
Company's mains. This well wes “drillcé in®™ on August 23, 1919, 
Vory little time was lost and very little gas wasted 
in getting the wolls connected to a distributing company's lincs 
as scvceral such pipc lines passed through or nearby the pool, 
Most of the wells in the Me¥cesport pool obtained their 
gas from the Speechley sand, although some obtaincd © gooc supply 
of gas trom the Murrysville, some from the One Hundred Poot and 
some from the Elizabeth sands. The Sneechiey sand lies about 


3270 fect below the Pittsburgh coal and has an average thickness

Several wells have been drilled to the Bradford sand but no gas 


was obtained, 
PRODUCTION 


The daily production, total nroduction, nuxnber of pro- 
cucing and cry wells, “closed-in" pressure, and average pipe line 
pressure are shown graphically on the acconmanying chart. . The 
daily and total production of the Poster ana Brend le-Yamilton 
#O well is also shown on this chart. 

To those not familiar with the use of graphic charts 
the following explanation will be helpful: from the attached 
chart one can observe the daily production for any dey desired 
trom August £9, 1919, to December 31, 1920, For example, 
November 10, 1919, gives the peak or "big day” produetion for 
the pool, namely 71,530,000 cubic feet of gas. Just above the 
daily »roduction curve is shown the graph of the number of oro- 
dueing wells. On that aay the number was five, The average 
daily production ner well at this time was 14,306,000 cubic feet 


of gas. On the total production curve at November 10 is given

the emount of gas the fielé has produced to that time, nomely 
3,725,939 000 cubic feet. The pressure curves for the seme da ‘te 
Show the “closed in” pressure to be 900 pounds per sevare inch, 
anc the average line pressure to be 250 wounds ver square inch. 
The daily production of the "big" well can be read in the same 
manner 2s the daily production of the ficld and is 42,772,000 
eubic feet; its total production to November 10, 1919 wes 
5,336 ,423,000 cubic feet of gas. In like manner the behavior 
Of the whole field can be had for any day during the sixteen 
producing months. | 

On May 1, 1920, the daily production from 90 wells 


, 


was 32,900,G00 cubic teet of gas, and the total production to 


> 
that cate was 12,792 “100,000 cubic feet with 119 dry wells in 
the field. The "closed in” pressure was 130 pounds per square 
inch while the average line pressure was about 25 pounds, The 


daily production of the Foster 2nd Brendle-Hemilton #3 well was 


nothing, as the well was being cleaned out. Total production 


4 


- 


of this well to May lst was 5,708,137,000 cubic feet. Hence 
tO May 1 the "big" well produced 44,6% of all gas produced from 
the pool, 

As one observes the chart closely it can be seen that 
e« well or group of wells being tumed in has a noticeable effect 
on the rise and fall of the daily production curve, The pro- 
duction from November, 1919, remained more or less constant, 
declining slightly until February 1, 1920. At that time twenty- 
eight wells were producing instead of five as on November 10, 


191$. The daily production on February 1, 1920 was 64,000,000

nineteen (419) welis had been oluecvec. and one hundrec and seventy- 
Seven (177) wells were ororucing 9,618,000 cubic feet of gas a 

Gay with = total production to thet date of 16,444,444 ,000 eubic 
feet of gas. On this same date. the Toster and Rrendle-Hemilton 


fo well was producing 354,000 cubic feet of gas daily with 2 total 


‘ 


a 


production of 5,725,771,000 cubic feet. This well has produeec 
$4.8% of all the pas »rocucec in the pool. 

At the close of the year 1920 there were 180 wells 
still producine ges in the pool with 441 wella ary. Tne’ procuc- 
tion ror the month of Jecember was 293,211,000 cubic feet or an 
averaze of 9,460,000 cubic feet daily, te tote production

It may be of interest to commare this curve with the 
statement made’ by the State Ccologist in his press bulletin of 
Mecember 29, 1919, “If this recuetion (of rock pressure) eon- 
banuies,; and the numbor of wells now boinc’ drilled would seem to 
Syisure its’ continuance, it ean rozcily bo calculetce how long the 
pressure will ‘be sufficient to drive the gas into the pipe line. 
Inceed were that recuc tion un continue to the end, it would ; 
mucicave the total life .of the -ficld to be nine months. As 2 
matter of fact, as the output of the field decreases with the 


deerease of »ressure, the curve of production tends to flatton

$0 that it may be between one and two years and possibly a 
little longer before the field is abandoned," In the later 
more detailec report, dated January 12, 1920, the State 
Geologist said, "It is estimatec that the Long Run Pool 
(Mekeesport Pool) did not contain at the beginning over 

15 to 20 billion cubic yveet of gas." 

In 1906, Pemsylvania reachec its maximum yearly 
production ot netural gas which was 138 billion oub ic feet. 
In 1918 the yearly production was 123 billion cubic feet. 

West Virginia's maximum yearly prouuetion of 
natural gas was zeachec in 1617 and was 308 billion cubic 
feet, which cdeclinedc curing the year 1913 to 265 billion 
cubic feet, 


The MeXeesport Gas rool in the year from August 


,29, 1919, to Ausust 29, 1920, wroduced 15,255,100,000 cubic 


feet of gas or 11% as much gas as the big yeer for Pennsyl- 
vania and nearly 5% as much gas as West Virginia produced

PRESSURE AND FLOW. 


Phe rock pressure and the onen flow are the two common 
factors in determinin: the cenacity of ges wells. The term ‘roe’ 
pressure" is usec to cesienate the pressure under which the cas 
occurs in the sand. It is measuread in »ounds per scuare inch by 
means of a gauge attachec to the well enc read when the »ressrre 
has attained a maximum after the well has been closed for 48 hours 
Or longer, The “open flow" of the well is the volume of sas de- 
livereé against atmospheric pressure in a given length of time. 

It is ceterminea by mea surin? the pressure or velocity of. the gas, 
from which the Saline may be conmputed. 

The volume of gas celivered by @ well under a given 
‘onen flow" pressure cenends nartlr on eacn or three factors: the 
Ciameter of the casing, the depth of well, and the porosity ond 
thic:mess of the sand Since in the McKeesport pool the size of 
Casing and depth of the vells were nearly all the same 
the difxerence in the flow of neighboring wells mey be ascribed to 
aifiference in porosity of the sands from which ther draw their 
Supply, -The rock pressure, on the other hance, is not arrected by 
minor variations in the porosity of the sand, and the whole body 
of gas in a pool of mo-erate size is theoretically under about 
the same rock pressure. 

If two neighboring gas wells, one producing a large 
volume anc the other a small volume of ges are closec, the rock 
pressure registerec by both will be about the game, but the larvzer 
well will register this pressure almost immeciately, whereas the 


smaller one may remain closec for Some time before its >»ressure

reaches the same figure. haut ore, a high rock pressure does not 
necessarily mean a high flow, but on the other hand 2 high flow 
is usually cecomanied by a high rock pressure, and the open flovy 
and pressure decline at sbout the sare rate. 

The flow of a well is greatly influenced by local cons 
ditions, such as the porosity of the sand, thickness, ete., bu% 
the pressure decline in a smll pool is a very accurate index of 


the stage of exhaustion of its reservoir of gas. 


EPFECT OF PUMPS ON PRODUCTION 

About June 12, 1920 the Peoples Natural Gas Company 
bergan operating their pump station on the Mekeesyort Gas Fool, 
BY means of the pumps the pressure at the wells was lowered and 
lowered until at tne present time the pumps heve reachec on 
eleven inch vacuum. The pumps did not increase the daily pro- 
duction noticeably but did check the decrease and since then the 
decline has been very slow anc gradual. (See production curve) 

The Manufacturers fight and Heat Company put their 
pumps into operation on September 15, 1920, at which time a 
little increase in daily production was recordec but the prodvuc-~ 
tion is still on its downward course. They are operating on 
about an eight inch vacuum. 

It must be remembered that with the pumps operating, 
the volume of gas produced from time to time is a poor index 2s 
to the actual life of the pool. Notice the curve for thé past 
three months - the debline in production is very small, but on 
the other hand the effect of the pumps have created a vacuum 


from about zero to eleven inches. No doubt the production will

course this cannot go on indefinitely. 

The writer estimates that the commercial life of the 
pool will enc about June 1, 1921, and the totel procuction of gas 
Will be 18,000,0%0,000 cubic feet. The tcetal production of the 
Foster and-Brendle-Hamilton ;:3 well will be about 5,730,000, 000 
Cusic £t. ("Big™ well: will have produced 31.8% of all the gas.)

percentage of cenvletion of the pool follows:

In making use of the above figures it must be remen~

bearing on the production of the Foster and Brendle-Hamilton 33

line not being sufficient to care for the total discharge.
